推荐答案

有几种方法可以达到你想要的东西。如果我理解正确，您有一个列表视图和一个按钮。当你点击按钮，你要3 editTexts出现在并排的列表视图侧，使得它看起来像一个表。

There are a couple ways to achieve what you want. If I'm understanding correctly you have a listview and a button. When you click the button, you want 3 editTexts to appear in your listview side by side so that it looks like a table.

的最简单的解决方案是有你的列表项的布局，在listadapter充气，简单地用weightSum含有3 edittexts与layout_weight一个的LinearLayout =3=1和layout_width =0dp

The simplest solution is have your list item layout, inflated in your listadapter, simply be a linearlayout with weightSum="3" containing 3 edittexts with layout_weight="1" and layout_width="0dp"

所以你list_item.xml看起来是这样的：

so your list_item.xml would look something like:

<LinearLayout
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:weightSum="3">
    <EditText android:layout_width="0dp"
        android:layout_height="wrap_content"
        android:layout_weight="1" 
        android:visibility="invisible"/>
    <EditText android:layout_width="0dp"
        android:layout_height="wrap_content"
        android:layout_weight="1" 
        android:visibility="invisible"/>
    <EditText android:layout_width="0dp"
        android:layout_height="wrap_content"
        android:layout_weight="1" 
        android:visibility="invisible"/>
</LinearLayout>

然后，在onclick您的按钮，遍历列表行的孩子和可见性设置为可见。

Then, in the onClick for your button, iterate through the children of the list row and set the visibilities to visible.

对于动态添加行，请使用listadapter和收集，并使用notifydatasetchanged更新列表，当您的收藏收益/损失的物品。

As for adding rows dynamically, use a listadapter and a collection and use the notifydatasetchanged to update the list when your collection gains/loses items.
